IMPROVEMENT 1N SEEDING-MACHINES.

The Schedule referred to :in these Letters Patent and making pan cf the same.

Io all whom it may concern: l

Be it knownthat I, JAMES FmLAYsoN, of Albany,

in the county of Linn, and State of Oregon, have illvented a new 'and useful Improvement in` Seeders'; and I'do hereby declare that the 'following is 'a full, clear, and eXact description of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specifi# cation, in which Figure l is'a transverse vertical section;

Figure 2 is a plan view of the machine inverted; and

Figure 3 is a partial front elevation, showing-the regulating-device. I

This invention consists in combining with the spring, whose office it is to guard the holes for the escape of grain in the bottoni of the seed-box, a horizontal shaft, under the seed-box, providedvwith a suitable number of spurs, and rotated by belt or other connection with the drivingwheels,'in such manner-'that said shaft may be niade-to'approach 'the lower ends of the spring, near enough to allowits spurs to displace them suciently to open the Y and allow seed to drop; and that said shaft may be made to recede from the lower ends of the springs vfar enough to allow the latterto remain in place, and prevent any seed from dropping, there being also provided a device for regulating thedistance to which the springs may be opened, and thus control the dropping of the seed, with respect to its amount.

In the drawings- I i A is the seed-box, having the usuall row of holes, a,'in its bottom, saidA holes heilig' guarded by springplates a', fastened at their upper' ends-to the insideof the fr'ont of the seed-box, and projecting downward- 4through thelio1es-a,'so as toy close them,

A bearing against their rear sides, and extending far enough be- .low the bottom ofthe seed-box to-'be within reach of v the spurs b', on. the horizontal 'shaft l), supported beneath the seedbox in end plates b'f, sliding transf versely of the box in guide-ways b", vprojecting .downward from the ends ofthe latter;

The shaft b may be drawn near enough to the spring a to permit its prongs b', as they rotate,vto strike the lower ends of said springs, and thus intermittently grain-holes which they guard,

open the holes a, the springs closing them again by their own recoil, after the passage of the spurs.

`If it be desired that no' seed shall'be sown, the shaft b is to be drawn away from the springs a', so-far that its spurs may not reachv them.

This movement of the shaft b is ei'eoted by means of a lever, @having its fulcru'm ou the outside of the front of the seed-box, and pivoted at its lower end to a horizontal rod, c', the extremities of which are jointed tothe front ends of elbow-levers c, th'e latter having their fulcra in armsof the brackets or guide-,ways b".

The inner ends of the elbow-levers c have teeth upon them, which teeth'engage with other teeth made in the sides'of the sliding end-plates b".

4On moving,by means of the lever c, the rod c',

vshown in fig. 2, to the left, the elbow-levers'c throw the sliding plates bvl and shaftb forward suficientl y far to bring the prongs bwithin impinging distance of the springs a.

The shaft b being rotated by means of a wheel on one end, connected by belting with a wheel, e, on the driving-shaft, eects, in the' manner set forth, the dropping of the seed. On moving the rod c' to the right, the dropping ceases.

L 'Fig 3 shows the vreguilating-apparatus, consisting of a slotted bar, h, upheld at one end by a set-screw,

h', and at the other end .by socket h", in which the bar may slide, andvhaving a stop, h', on its front side, to

limit the throw ofthe lever c,

The farther 'the lever. c, in fig. 3, is 'moved toward the right, the wider the 'grain-holes in the seed-boit are thrown open, and the more seed is dropped.

Having lthus described my invention,

What l claim as new, and desire to secure by Letters Patent, is`

l. The adjustable shaft b, provided with the spurs b', in combination with theY springs a', substantially as set forth. y

2.' The slotted bar h, provided with a, stop, in combination with the lever c, substantially as specified.

The above speoiiication of my invention signed by me, this 30th day of January, 1869.
